Specification of Letters Patent.

Patented June 30, 1908.

Application filed November 20, 1907. Serial No. 103,094.

To all whom it may concern:

Be it known that I, GEORGE B. FoUsT, a citizen of the United States,residing at Masontown, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements in Coke-Extractors, of which the following is a specification.

My invention relates to machines for draw ing coke "from coke ovens, andfor other like uses. It is desirable, in most cases, that the frameworkand mechanism of such machines shall be such that the entire apparatus,including a delivery conveyer hereinafter mentioned, may be mounted uponand sup orted solely from a single truck of short'whee -base, so thatthe machine may be self-contained, easily moved on tracks whether thelatter be straight or curved, and easily turned about.

It is also desirable that the machine shall be capable of delivering thecoke or like material at a point considerably to one side of the suporting truck and at a level consid erablybigher than that at which thematerial is received, so that, for example, high-sided cars may beloaded by means of it. The machine herein described and illustrated inthe accompanying drawings fulfils these requirements.

- The said machine comprises a suitable four-wheeled truck of shortwheel-base, carrying a derrick-frame for the support of a cantaliverconvcyer, and it also comprises the usual ram supported on the saidtruck and arranged to be moved into and out of the coke ovens orfurnaces and provided with Owing to the fact that it is desirable todeliver the material at to su port the rear or receiving end of the said(I ivery conveyor at a level considerably above that of the said ram,and provide elevating means for receiving the material as drawn out bysaid ram and raising it to a point where it will fall by gravity on tosaid conveyor. This elevating device, according to my invention, is anannular bucket-wheel, of trough-section, entirely open at the center,that is to say, entirely devoid of spokes, so that the said Work throughthis open center and so that the receiving end of the conveyor may alsobe within this open center. This bucketwheel is "provided with bucketsor shelves constructed and arranged to discharge the material carried upby them when a point over the conveyer is reached.

In the accompanying drawings: Figure 1 shows a front elevation of themachine, that is to say, an elevation of that side which, when themachine is in use, is toward the oven from which the material is to betaken. Fig. 2 shows a top view of the machine, and Fig. 3 a sideelevation thereof. Fig. 4 shows a vertical section of the elevatingwheel in the plane of rotation thereof; Fig. 5 a detail front view of aortion of said rim, showing the means for he ding closed normallycertain supplemental filling-doors hereinafter mentioned; and Fig. 6 adetail horizontal section showing means for adjusting said elevatingWheel. Fig. 7 is a view similar to Fig. 1, illustrating an alternativemounting for the elevating wheel.

In the drawings, 1 designates a fourwheeled supporting truck of shortwheelbase, and 2 a derrick-frame thereon. At the top of this frame aretransverse braces 3 upon which are mounted sheaves 4.. over which passthe ropes or cables 5 for su1 porting the outer end of the overhangingor cantaliver liver convcyer, above mentioned.

For carrying the said elevating wheel, I provide an upright rectangularframe, A, carried by the truck 1 and preferably overhung (see Fig. 3)and supported by brackets 6 secured to truck 1. Said frame A comprisestop and bottom members 7 and 8 respectively and side members 9. In thecon struction shown in Fig. 1, the elevating wheel is not supporteddirectly upon this frame A, but upon a movable secondary frame B,movable from side to side (that is to say, in a plane substantiallyparallel to the plane of rotation of the wheel) for the purpose ofadjusting the position of said wheel. In the construction shown in Fig.7, however, this means for adjustment is omitted, the elevatingwheelbeing mounted directly on the frame A. In the construction shown inFig. 1, frame A is provided with cross-pieces 10, 10 (Fig. 1) 11, 11"

(Fig. 3) which, with bottom members 8 of frame A, form rails upon whichthe secondary frame B may move as described. This secondary frame Bcomprises top and bottom members, 14 and 15 respectively, and sidemembers 16, and is provided with flanged carrying-wheels 17 and 18,arranged to roll along members 10 and 11, and 8, respectively, of frameA. Members 10 and 11 constitute keepers to prevent derailment of -rameB. Frame A further comprises cross-pieces 12, upon which are mountedother sheave-wheels 13 for cables 5. 25 designates the said annularelevating wheel, of trough section. It is supported and guided inrotation by grooved carrying-rollers 19 mounted on shafts 21 mounted inbe'arfifgs in frame B (in the construction shown in Fig. 1) and in frameA (in the construction shown in Fig. 7). These carrying-rollers 19 arefree to slide longitudinally upon their shafts, for reasons hereinafterexplained. The elevating wheel 25 is rotated by means of a gear 26,carried by it, and by a pinion 20 mounted on one of the shafts 21; whichshaft and pinion are arranged to be rotated by suitable means, as forexample a sprocket chain 22 engaging a sprocket wheel 23 on said shaftand driven by a motor 23 on truck 1. Wheel 25 is provided with internalpartitions or buckets 37; and to permit adjustment of the point at whichthe material carried up by these buckets is discharged upon theconveyer, each bucket is provided with a hinged section 38, pivoted at38, and arranged to be adjustably locked in various difierent angularpositions by means ofsliding locking-bolts 39 adapted to enter one oranother of corresponding locking-holes 40 in the side of the wheel; (seeFig. 4).

In order that the coke or other material, as pulled out from the oven orfurnace, may enter the trough of wheel 25, I- provide the inclined apron41, the outer portion of which should be at approximately the height ofthe sill of the oven-door; said apron being inclined so as to deliverthe material into the trough of wheel 25 at or near the bottom of thewheel. This apron is supported by brackets 42 (Fig. 1). In order topermit the easy introduction into the trough of the wheel of materialwhich may miss the apron 41 or fall from the sides thereof, I provide inthe sides of wheel 25 inwardly-opening traps or doors, 27, 27, and 28and 28, of which one set, 27 and 27 is to be used when the wheel rotatesin one direction, and the other set, 28 and 28, is to be used when thewheel rotates in the opposite direction; and I further provide troughs35, at the sides of wheel 25, into which troughs the material missing orescaping from the apron 41 may be shoveled or otherwise introduced, andfrom which said material will slide into wheel 25 through the doorwaysin the sides of the wheel when the doors, 27 and 27, or 28 and 28, areopened opposite the ends of said troughs, as presently described.

Doors or traps 27, 27, 28 and 28 are held closed normally by leafsprings 30 (Fig. 5) engaging pins 31 extending from said doors or trapsthrough arc-shaped slots in the front of the wheel 25. When the doors 27and 27 or 28 and 28, (according to the direction of rotation), comeopposite the corresponding trough 35, lugs 32 carried by,

these doors engage cams 33 carried by arms 34 secured to the framework,and are forced inward, so opening said doors momentarily and permittingmaterial which has accumulated on the trough 35 to slide therefrom intothe wheel 25. In practice only one cam 33' is in operative position atany one time, and when the direction of rotation of Wheel 25 is to bechanged the cam 33 is shifted to the other side of the frame-work; andcorrespondingly, only one set of doors, 27 27, or 28, 28, is providedwith lugs 32 at any one time. As soon as adoor has passed the end of thecorresponding trough 35 its lug 32 slips off from the cam 33 and thedoor is closed by its spring 30. That set of doors which are not to openare held closed by rods 36, Fig. 4, seated at their ends in holes in thefront and rear of wheel 25.

The secondary frame, B, is provided to permit good adjustment of theposition of the wheel 25 and apron 41 with respect to the door of theoven or furnace. Such adjustment is effected by moving frame B for wardor back, with reference to frame A, by screw 24 (Fig. 1). But in somecases provision for such close adjustment may be considered unnecessary;in which case the secondary frame B is omitted, as shown in Fig. 7. Theframework is somewhat wider than the elevating wheel 25, to permitadjustment of said wheel toward and from the oven; for which reason,also, carrying rollers 19 are free to slide on their shafts 21; and toso adjust the wheel I provide a pivoted lever 43 (Fig. 6) having at itsend nearest wheel 25 a slot' 44 in which works a pin of a collar 45seated in a groove in the hub of the adjacent carrying roller 19. When.wheel 25 is rotating it is an easy matter to move wheel 25 1 1 toward orfrom the oven by means of this lever 43.

The rake, 48, which is adapted to enter the oven or furnace and thenmove backward,

drawing with it the coke or other material I be of usual construction,and may be operated by usual mechanism, and requires no detaildescription here. The delivery conveyer, 49, which is an ordinary linkconveyer, is supported at its receiving end upon frame-member 50, asshown par ticularly in Fig. 1, and is supported at its outer end by thecables 5 and counterweights 5 secured to said cables. By means of thesecables and counterweights the outer end of the conveyer may be raised orlow ered through a considerable distance, so permitting the height ofdelivery to be varied considerably. This conveyer, and also the rake48,pass ter of wheel 25, as indicated particularly in Figs. 1 and 3; whichis the prime reason why said wheel 25 is an annulus, rather than aspoked wheel. Passing the rake directly through the open center of thewheel 25 therein, may

directly through the open,cen'

' provide side makes it particularly easy for said rake to pull back thecoke, etc. directly into the apron 41 and said wheel. The conveyer 49being directly beneath that part of wheel 25 at which the material isdischarged, the ma terial of necessity falls directly on the conveyer.To prevent the material from'falling oil from the conveyer, so far aspossible, I

and springs 47 which hold the wings in proper position, normally, and atthe same time prevent blocking of the mechanism in case a piece of cokeshould become stuck between the side of the conveyor and wheel 25.

The operation of the machine is as follows: The machine being opposite asuitable oven or furnace and the wheel 25 and conveyer 49 being inoperation, the rake 48 is moved into the furnace and is then drawn outagain, in the ordinary manner, and as it moves out it draws with it cokeor other material within the furnace, causing such coke or othermaterial to fall upon apron 41 and to slide into wheel 25. Such materialis then carried up ward by wheel 25 in its rotation, owing to thetroughshape of the wheel and its buckets or partitions 37; and as thematerial reaches a position over the conveyor 49 it falls upon theconveyer, (the particular point of such discharge being regulated byregulating the angle of the hinged sections 38 of partitions 37), and iscarried oll by said conveyor and discharged. Coke or the like whichdrops from or around the machine is shoveled into the proper trough 35,and as wheel 25 rotates, the doors 27 and 27, or 28 and 28, openautomatically when opposite said trough 35, permitting the material onsaid trough to slide into Wheel 25; after which said doors close.

The hinged sections 38 of buckets or partitions 37 not only permitregulation of the point at which discharge of the material from wheel 25upon the conveyer takes place, but makes easy adjustment of the wheel 25for rotation in the opposite direction, by reversing the angle of thesections 38. In Fig. 4 I indicate in dotted lines such reversed positionof one of the sections 38.
